Now i want to draw a part of this image, such as draw the image within a rectangle rect(360, 420, 240, 280). Is there a simple method to do this? Best Regards, chen Re: Draw select part of the bitmap Christian Graus12-Jul-02 21:07 Christian Graus 12-Jul-02 21:07  BitBlt and StretchBlt both allow you to specify the part of the image to draw.

I can't seem to find any. -Raffi Need for speed neilxp12-Jul-02 16:28 neilxp 12-Jul-02 16:28  I have a class which can calculate a mathematics expression,such as "sin(x)+cos(x)",when given a number to x, it could return the value of the expression.It works in two steps:At first,it parses the expression,and then,it calculates.I have a list of x's values,all of them are used in the expression "sin(x)+cos(x)",so they are calculated in the same way,but the class parses the expression for each x value,you see, it does the same work many many times.What can I do if I want the class to parse once but calculate all? Re: Need for speed Christian Graus12-Jul-02 17:11 Christian Graus 12-Jul-02 17:11  Make a static array, which is a lookup table. Then each sin or cos is calculated exactly once.

Can anyone suggest a good Lint Checker? Really, I would love a free one?? Thanks ! Philip Re: Lint for C++? Neville Franks12-Jul-02 23:55 Neville Franks 12-Jul-02 23:55  Lint may be of some use, but I'd surprised if it would pinpoint your crash. Have you tried running a Debug Build under the VC Debugger and inspecting where the crash occures when it happens? Also have a look at the various BugSlayer articles by John Robbins on the MS MSDN Web site http://msdn.microsoft.com/default.asp and "Improved Error Reporting with DBGHELP 5.1 APIs" http://msdn.microsoft.com/msdnmag/issues/02/03/Hood/Hood0203.asp Neville Franks, Author of ED for Windows. www.getsoft.com How to copy char array to BSTR Shanti12-Jul-02 14:53 Shanti 12-Jul-02 14:53  This is a new one for me. I have a buffer, i.e., char buffer[100]. I need to copy the contents of the buffer into a BSTR that is already allocated and already has a value. Basically, I need to change the value of the BSTR before I send it to another method that requires a BSTR. I cannot figure out how to do this? Any advice? Thanks for any help, Shanti Re: How to copy char array to BSTR Christian Graus12-Jul-02 15:16 Christian Graus 12-Jul-02 15:16  comutils.h includes a wrapper class called _bstr_t. You can do this: HRESULT MyFunc(/*[in, out]*/BSTR * bstr) { _bstr_t b_tWrap(*bstr, false); // FALSE means the _bstr_t takes ownership b_tWrap = mycharbuffer; *bstr = b_tWrap.Release(); } Something like that.

But, how do you do it in C? Also, how would you convert a BSTR or Variant to a char buffer?. Kind of hard to find examples on how to do these things in C cuz all examples in MSDN etc. only use C++. I'm modifying an existing C program to use COM/OCX and keep running into these kinds of problems.

I'll give that a try. assert trying to MoveWindow() ns12-Jul-02 11:16 ns 12-Jul-02 11:16  Hi I'm trying to reposition like so: void CForm2View::OnSize(UINT nType, int cx, int cy) { CFormView::OnSize(nType, cx, cy); m_editbox1.MoveWindow(0,0,cx,cy,TRUE ); } except that I modified the code at http://www.codetools.com/docview/centermdiwnd.asp to make the CFormView fit exactly and immovably in my MDI frame (took away draggability of the view as well). The above is causing a debug assertion. The foll shows the messagebox but doesnt like setwindowtext either: void CForm2View::OnSize(UINT nType, int cx, int cy) { CFormView::OnSize(nType, cx, cy); //MessageBox("aaaa"); // m_editbox1.MoveWindow(0,0,cx,cy,TRUE ); m_editbox1.SetWindowText ("moving!!"); MSDN says: Example // Resize the list control contained in the view to // fill the entire view when the view's window is // resized. CMyView is a CView derived class. void CMyView::OnSize(UINT nType, int cx, int cy) { CView::OnSize(nType, cx, cy); // Resize list to fill the whole view. m_List.MoveWindow (0, 0, cx, cy); } So I am confused. Please respond! Re: assert trying to MoveWindow() Raphael Kindt12-Jul-02 14:07 Raphael Kindt 12-Jul-02 14:07  I see... The problem is that OnSize() is call a first time when the view is created. I tested that with a simple dialog based containing a button... And it's OK... bool m_bWait => a member of CMyDialog (which is a CDialog derived class) CButton m_ctrlButton => a member of CMyDialog class CMyDialog : public CDialog { public: CMyDialog(CWnd* pParent = NULL) { ... m_bWait = false; // initialize in the construtor } ... } void CMyDialog::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); if(m_bWait) m_ctrlButton.MoveWindow(0, 0, cx, cy, TRUE); m_bWait = true; } I hope that can help you Hello World!!! from Raphaël Re: assert trying to MoveWindow() Christian Graus12-Jul-02 15:17 Christian Graus 12-Jul-02 15:17  Yuck. Much better to do this: void CMyDialog::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); if (::IsWindowVisible(*this)) m_ctrlButton.MoveWindow(0, 0, cx, cy, TRUE); } Christian come on all you MS suckups, defend your sugar-daddy now. - Chris Losinger - 11/07/2002
